Concentrated Solar Power for Industrial Heating
Industrial sector is one of the largest energy consuming sectors.
Industrial energy demand is met by electricity, coal, oil, gas, and biomass.
Major industrial end energy consumption is thermal energy (process heat).
Concentrated Solar Power (CSP) technologies can provide the required heat for
these processes.
Heat is provided at the user point through a working fluid which is generally
pressurized hot water, steam, hot air or hot oil.
CSP systems have been used for cooling, food production, steam cooking, baking of
bread, hot water / steam, and evaporation.
Parabolic dish with moving focus is one such CSP system, and in India ‘Arun Dish’ has
been commercially used in various sectors.
Case Study: ‘ARUN’ in Dairy Industry
The dairy industry utilizes a large amount of energy for milk processing, pasteurization,
sterilization, cleaning-in-place (CIP), etc., which is in the form of medium temperature thermal
energy, which can be provided through the use of solar concentrators.
Mahanand Dairy (situated in Maharashtra, India) opted to satisfy its thermal energy needs through
solar energy in its pasteurization process, and installed a solar thermal system in 2006.
The system was developed by Mumbai based Clique Solar. The completely automatic two-axis
tracking system ensures maximum efficiency. ARUN160 has an aperture area of 169 sq. m.
On a clear shiny day, a single ARUN dish delivers sufficient energy for pasteurization of ~30,000
liters of milk and CIP of milk storage tanks.
An insulated pressurized water storage tank has been provided for storage of thermal energy.
Pressurized water was selected as the medium of heat transfer and storage, as it has high specific
heat, no fire hazards, compatibility with food products and low operational cost.
Case Study I: ‘ARUN’ in Dairy Industry
Operation
In the morning, the circulating pump extracts water from the storage
tank and circulates it through the receiver coil.
The water is then heated and sent back to the storage tank. The water
is stored at a pressure of 18 bar, at 180°C.
The hot water then flows through the heat exchanger to transfer the
heat to the milk for pasteurization.
The milk gets pasteurized using the hot water generated by the
concentrated solar thermal system
This system continues to save about 100 to 115 litres of furnace oil on
a clear sunny day (~ 20,000 liters of furnace oil per annum ).

MSW to Power – Chinese Case study
In 2002, the Wenzhou city government (Zhejiang province), decided to form a
partnership with a local private contractor, Wei Ming Environmental Protection
Engineering, to build, own and operate a new MSW-to-energy incinerator plant
under a build, own and transfer (BOT) scheme.
The company invested a total of CNY90 million ($10.863 million at an
exchange rate of 0.1207 $/CNY for 2002) in phases to build the plant and
operate, manage, and maintain it for a period of 25 years (excluding a 2-year
construction period) under the BOT agreement.
At the end of the period, the plant will revert to government ownership without
any additional compensation to the company. The plant has been operational
since 2003.
The incinerator plant has a design capacity of 320 tonnes of MSW per day
and electricity generation of up to 25 million kilowatt-hours annually.
MSW to Power – Chinese Case study (contd.)
The plant receives a service fee from the Wenzhou city
government for the disposal of MSW at a rate of CNY 73.8 per
tonne ($10.13 per ton at an average exchange rate of 0.1372
$/CNY for the period 2003 to 2013).
The BOT project is expected to break even after 12 years.
The project has received support in the form of network
operators purchasing electricity generated by the project,
exemption from corporate income tax for the first 5 years of
operation, and eligibility for immediate refund of value-added
tax.
In Zhejiang province alone, more than 30 such plants exist in
cities such as Wenzhou, Jiaxing, Shaoxing, Hangzhou, Ningbo,
Jinhua, and Taizhou.

MSW to Power – The Indian Experience
Local municipal administration (Corporation / Municipality) is responsible for the collection,
transportation and disposal of municipal solid waste (MSW) generated in the city as per the
procedure laid down under MSW (Management and Handling) Rules 2000 framed by the Ministry
of Environment and Forests (MoEF).
Administration with an intention to develop project facility for treatment and disposal of the waste,
invites proposals from the private sector after floating the Request for Proposal (RFP).
The selection has been done competitively on the basis of the highest tipping fee quoted by private
developers to be received from the administration for disposal of waste.
In general, developers get the required land from the administration at negligible cost.
Developers have the freedom of selecting the technology for waste processing, and can
commercially use the by-products derived from the delivered waste.
Administration has to ensure a minimum MSW supply to the developers, and developers can face
penalty if they cannot handle waste in the required quantum.
Electricity is generated from such plants after processing the waste, and using different technologies
for power generation (biomethanation, gasification, or incineration).
MSW to Power – The Indian Experience
Developers can sell the power to electricity utilities, interested
third parties, traders, or power exchanges.
The electricity sale rates w.r.t. utilities have been determined by
the Electricity Regulatory Commission as project specific tariff
after scrutinizing the detailed project cost.
These projects can also get benefits under Renewable Energy
Certificates (REC) and can earn revenue through RECs.
Other benefits related to RE projects such as income tax holiday,
and accelerated depreciation are also applicable.

Pune Municipal Corporation (PMC) floated RFP for waste processing
Rochem Separation Systems won the bid on the basis of tipping fee
PMC guaranteed 700 TPD MSW supply and gave land for the project
Rochem quoted INR 300 / tonne as tipping fee to be received from PMC
Rochem designed the project on pyrolysis-gasification technology
The project capacity is 8.97 MW (2.99 MW X 3)
15% of the energy generated is used as auxiliary consumption
The remaining is sold to the utility
PRECONDITIONING
Community-based Small Wind Turbines:
Case Study from Peru
The inhabitants of Alumbre in Northern Peru are mainly engaged in subsistence
agriculture and livestock rearing.
The electrification project through small wind is designed to cover basic household
needs and community services (school and health centres).
In the first phase, 21 wind turbines of 100 W were installed in 21 homes and a wind
turbine of 500 W was installed in the local school. In the second phase, 14 more
family systems and a 500 W wind turbine were installed to electrify homes and the
health centre respectively.
The region is characterized by low to moderate winds, and the wind turbines installed
are specifically designed to operate at low wind speeds.
A local micro enterprise was formed to operate, maintain and administer all the
systems. The micro-enterprise-based management model promoted active
participation of beneficiaries, representatives from the enterprise, and community
leaders.
Community-based Small Wind Turbines: Case
Study from Peru (contd.)
The micro enterprise is legally registered as a sole proprietorship, and has a
monthly tariff structure. The micro enterprise is in charge of collecting the
monthly tariff paid by the users, and the tariff serves to cover the costs of
maintenance and replacement of the equipment throughout the lifespan of the
project. The tariff also serves to provide a stipend to the operatoradministrator.
The wind turbine installed in each home covers the domestic use of electricity
for 5 hours/day. The households use the turbines for lighting, weaving or
knitting in the evenings, operating the radio and charging cellphones.
The turbines in the school power four computers and a DVD player for
educational videos used by students from Alumbre and neighbouring
communities.
Community-based Small Wind Turbines: Case
Study from Peru (contd.)
The health centre, which attends to people in four communities,
now has electricity for lighting purposes and for running a
vaccine refrigerator.
Community training sessions for authorities and local
technicians strengthen operation and maintenance.
Use of wind turbines has reduced the expenditure on other
energy sources such as kerosene and candles.
Families have been using energy directly or indirectly in the
implementation of small business such as operating a radio
station, producing sweaters, and cheese making.
